While a NAS usually (always?) has some method of remote configuration, a USB version of the same drive usually won't. The NAS requires configuration to know its IP address among other things. A USB drive does not require configuration.

I would be surprised if you have any choice other than some opaque tape or other opaque object to block the LED. Sorry.

In all seriousness, I've never seen a USB enclosure with any configurable options. Reason? Well, a NAS must have a back-end management solution (creating arrays, permissions, etc) which all require expensive (in context) hardware (web server, etc). A USB caddy is a "Dumb" device, it just sits there and translates instructions. It has no back-end configurations.

I can just imagine the looks if someone saw a bottle of black nail polish in my desk drawer... ;)

Better be careful, as nail polish has acetone, which is an excellent solvent for many plastics, usually those employed in PC cases.

Nail polish remover contains acetone, typically not the nail polish itself. Nail polish is normally nitrocellulose based with butyl stearate or butanone used as the solvent. They are not very aggressive solvents like acetone is. LEDs themselves are typically encased in clear epoxy which is resistant to the vast majority of solvents. That said care should be exercised with any paint that is solvent based and test it in an inconspicuous area first.
